In this sequel to Hammerfall (2001), the story of an important desert planet that was nearly destroyed by the alien Ondat continues. Marak Trin Tain is the planet's leader and a key figure in maintaining the tentative treaty between human and alien powers. The focus here is on Concord Station, which monitors the tiny planet at the edge of the galaxy and is the fulcrum of the precarious balancing of peace and power between two intergalactic empires. Because of past associations, Procyon, a young watcher monitoring the planet, becomes the object of intense interest for the major powers, Marak, and the leaders of the planet's underground movement, which has its own agenda.
